Good catch. If modeling is not installed, then the code formatting doesn’t get installed either because (due to historical reasons) it’s part of that package.
You can check it’s definitely installed by right-clicking on an editor window containing some Delphi source code - the context window which pops up should have the format source option in it.

If that is showing but the shortcut is not working, then it’s definitely an add-in or the keyboard shortcut has somehow not been bound to that function.
If the function doesn’t appear in the right-click menu then it’s not installed and you need to save your project (and close it) then from the main IDE window select tools–>manage features.
The installer window will open, scroll down until you see modeling - and make sure it’s checked. Then let the installer do its stuff.
